ITEM NO.: 90-4-1

Proposed California Clean Air Act Guidance for the Determinationof Reasonably Available Control Technology (RACT) and BestAvailable Retrofit Control Technology (BARCT).

RECOMMENDATION

We recommend that the Air Resources Board approve the ProposedGuidance and direct the staff to begin the process fordetermining RACT and BARCT for existing sources in cooperationwith the districts. We also recommend the Board direct itsExecutive Officer to notify the districts that the ARB will beusing as a starting point the RACT and BARCT determinations basedon this guidance in reviewing for approval district plans andrules. DISCUSSION

Background

The California Legislature enacted the California Clean Air Act(CCAA) in 1988 (Stats. 1988, ch. 1568). Part of the CCAA wasincorporated into Part 3 of Division 26 of the Health and SafetyCode (HSC) as a new Chapter 10, District Plans to Attain StateAmbient Air Quality Standards beginning with Section 40910. Inthis chapter, HSC Sections 40910 and 40913(a) require thatdistricts develop attainment plans which shall be designed toachieve and maintain state ambient air quality standards by theearliest practicable date, as determined by the district boardand subject to the approval of the Air Resources Board (ARB).

To help the districts reach attainment, HSC Sections 40918through 40920 state that district attainment plans must includeregulations which require control technologies for existingsources. In addition, the HSC requires that ARB review districtattainment plans to ensure that:

1. RACT and BARCT will be determined and applied appropriately,2. the plans show that the state ambient air quality standards will be achieved as expeditiously as possible,3. the plans show that at least an average of five percent emission reductions per year of nonattainment pollutants will be achieved, and4. the plans include RACT/BARCT determinations that are uniform within air basins.

The HSC does not clearly define BARCT and contains no definitionfor RACT. Also, the HSC does not delineate the procedure fordetermining RACT and BARCT. The purpose of this guidance is tohelp districts in the planning process to implement the CCAA'srequirements for the application of RACT and BARCT. Thisguidance will also serve to help streamline the rule developmentprocess, ensure uniformity of rules within air basins and promoteconsistency of rules in similarly designated districts withindifferent air basins.

Research Plan: 1990 Update.

RECOMMENDATION

Adopt Resolution 90-26 approving the Research Plan, dated April,1990.

SUMMARY

In establishing the State's approach to achieving clean air, theLegislature: has declared that an effective research program isan integral part of the broad-based statewide effort to combatair pollution in California; has directed the Air Resources Boardto administer and coordinate all air pollution research funded,in whole or in part, with state funds; has directed the AirResources Board to establish objectives for air pollutionresearch; and has directed the Air Resources Board to appoint aResearch Screening Committee to give advice and recommendationswith respect to air pollution research projects funded by theState.

In order to comply with these mandates from the Legislature, theBoard meets, each year, with its Research Screening Committee, toreview the Board's research program, as outlined in the ResearchPlan. This Plan is prepared by the staff, with guidance from theResearch Screening Committee.

The Research Plan describes major ongoing research projects andnew projects to be funded in Fiscal Year 1990-91. More detaileddescriptions of the projects, a summary of recently completedprojects, and the Air Resources board's research budget forFiscal Year 1990-91 are shown in the Appendices.

This year's Research Plan features projects to support theBoard's activities to reduce emissions from motor vehicles;support the introduction of clean burning fuels; add to ourknowledge of the sources, fate and effects of toxic aircontaminants; provide bases for controlling stationary sourceemissions; better characterize the effects of agriculturalburning; improve our ability to analyze regional air qualityproblems, better define the effects of exposure to air pollutantson human health; and better define the extent of air pollutiondamage to all forms of vegetation.
